    Subject[RFC] [PATCH 1/16] x86_64: Align data segment to page size boundary

    o Explicitly align data segment to PAGE_SIZE boundary otherwise depending on
    config options and tool chain it might be placed on a non PAGE_SIZE aligned
    boundary and vmlinux loaders like kexec fail when they encounter a
    PT_LOAD type segment which is not aligned to PAGE_SIZE boundary.
